Outcome Measures

Primary Outcomes (1)

  • SPID (Sum Pain Intensity Difference)

    The primary efficacy parameter is muscle pain/soreness with movement at 48 hours (SPID 0-48)

    0-48 hours

Secondary Outcomes (3)

  • spontaneous muscle pain/soreness

    0-48 hours

  • Muscle stiffness with movement

    0-48 hours

  • Overall evaluation measures

    0-48 hours

Study Arms (2)

Placebo

PLACEBO COMPARATOR

2 capsules identical to comparator, 3 times daily on Day 1 and Day 2. On Day 3 only one dose will be taken. The intervention is Acetaminophen 1000mg.

Drug: Acetaminophen 1000mg
